The nose comprises a block 'of metal dated by,a adjusting device to provide for C having at its rear side astud C that is e10 55 diii'erent thicknessof stock. tended through a hole in the depending por- 00 stock, the driver having co-acting with it an loosely connected the u perend of afspot tion A of the head A. The stud is provided with a holewhieh is tapped to present a screw-thread that is entered by the shank of scribed, which raceway is sustained by a bar or arm 104 extended from the machine arm. The extension 0 has mounted on it a cover plate C, the latter having legs 105 and 106, each of which are attached to said extension by a suitable set screw to thus mount the cover plate above said extension for a distance sull'icient to enable a spot having ahead of a certain depth to pass under said cover plate. The top of the cover plate is slotted at 108 and, in this slot stands the spot. feeder. These noses are made ol dillerent sizes, a dif' ferent one -for each size of spot to be handled in the machine, and a hole 109 in the nose is of the diameter of the head of the spot, and by taking out the bolt AS", a nose of any dosired size may readily be substituted without disturbing: the raceway, which is a matter o'l" consideralile ini ortance, for Where the nose is attached by a screw or screws to the lower end of the raceway, the screws have to be removed and the raceway pushed back into the hopper;

The nose has a separable l'ront part held in place by a spring 10 the front part littins over two pins 200 carried by the back part ol the nose. The machine will be provided with a series ol noses having threats of dil ferent diameter according to the diameter oi the spot. and of the driver to drive the spot through said throat.

The spot feeder 3 is beveled from its lower end upwards and toward the driver, as at F/, so that when the feeder is depressed from its position Fig. 3, such beveled portion can move to the right. only far enough to come into ooi'ltact with the side of the driver next thereto at a point above the lower end of the driver, thereby i'n'evcntin g any possibility olthe feeder extending into the driver path. The spots leed down the raceway by gravity, and ordinarily tho-Weight ol' the spots behind it will be sulliciont to feed the loading or first spot into dotted line position, Fig. 2 in readiness to be pushed through the hole in the nose by the descent of the driver A. Supposing that the parts are in such position, then as the driver descends the spot leedcr will descend with it until it. engages with the second spot, whereupon the tender will be stopped, as the resistance to its downward movement, presented by the sor-ond spot abutting against the lirsl. spot, is sullicionl' to over ome the friction i'onnor't ion bei nus there.- no tendency to iorce two spots into the driving or setting; position. I

The main function of the feeder t?" is .o insure the )rescnce of a spot in proper position under the driver in case the spots in the racevniy should be too low in number to l'r-cd illt leading one beyond the full line position shown in Fig. 3, or in. case the loading: spot should be held by dirt or oil on the end ol the raceway. in such case the descent ol' the spot feeder with the driver acts to push forward into setting position the lending;- spot. But for these accidental stoppages in the natural feed of the spots the feeder t could be omitted, as will be apparent from the foregoing explanation. Should all of the spots but one have been led from the raceway, for instance, that last one might not move into the driver path, or it might move part way thereinto. and in the latter case would be smashed by the descent of the driver, but the feeder prevents such an :uscii'lnt by pusbing the spot forward into the proper position under the driver.

Prior to my invention the lower end of a tender has been turned to leave a lip toward the driver and under some conditions the lip is aut bt. by the drivcr in its dosront and the lender is broken.

the hopper they will turn naturally into such position, and I have utilizedthis tendency, in

mypresent invention, to facilitate the discharge of the spots from the hop er. That is, I have provided 'Ineans for ischarging them from the hopper legs up, and in such position they are introduced to the end of the raceway adjaccntan outlet in the stationary wall of the hopper, and as the spots travel down the raceway into osition to be set they are turned with their eggs down, as will be explained; The raceway is herein shown as comprising two leg-guiding 'lates cl, d and a head-covering plate (1 an the spots leave thehopper with their legs, up, one behind the other, to enter the space 2 between the plates (1, (1 Fig. 7, the spot heads traveling along the plate (1 at such time.

I found in practice that the raceway, (the plates of which are coiniected by screws (1 the plates d, d being separated from the plate (1" by hollow posts (1 could not be *ept properly filled with spots by the employment of an agitator comprising a revolu le' cross head having fingers 3-, 4, 5, at its ends that swee close to the inner wall of the curb and lift tlic spots so that they may in sliding down over the bottom I) of the hopper enter the groove (1 of the guideway leading to the raceway. Consequently 51 have provided a bridge D covering the lower end of the'guideway D, the bridge being shaped at its upper end to present a horn ii having a convexed or curved side (1 the up er en of the'bridge at the ri ht of the side. viewing Fig. 5, having a lieveled or inclined to d, presenting an edge (1 that meets practically at a right an le the guiding edge of the plate (1 whlch partly covers the grooved in the guideway The under side of the a bridge has a longitudinal groove d, Figs. 6

' end of the raceway.

and 8, starting as shown at the base of the converted side d of the horn, and leading through the bridge, above the lower end of the groove (1 and communicating, as will be described, with the" space 2 in. the raceway, so that when the spots are properly presented with their heads in the groove (1 and their upturned legs against the edge of the plate d the said legs-will enter and travel along in the groove d while the heads of the spots will travel through the lower end of the groove d, the legs finally passing out from the hopper through a slot or outlet 82 in the curb D to properly enter the space 2 at the receiving The lower end of the groove abuts against the curb, see Fig. 6, and the raceway comes up to the lower end of the grooved guideway D, as shown, and in salinement therewith.

Referring to Figs. 5 and 8, it will be seen that the guiding edge of the plate r1 projects over the adjacent edge of the groove d, the

transverse ower end of t to beveled part (1 of the bridge, and the exposed or open part d in Fig. 8. Supposing a spotjwithin the hopper to be deposited in the groove at, head down and with 1ts legs 11 turned, as the spot travels downward its egs will bring up against the curved side (1 of the bridge and the spot will be turned gradually so that when it reaches the entrance of the groove (1 in the bridge the legs will be directed into such entrance, one behind the other, the edge of the plate d being alined with the adjacent side wall of the groove (1 as shown in Fig. 8. The spot can. now pass through said groove in the bridge, its head sliding along the narrower part (1 of the trough groove, and passing out at its lower end, while the lows leave the groove (1 and pass out through the curb D by the notch or outlet 82. Thus the function of the curved side (Z of the bridge is to turn the spots and position the legs to enter the groove d so that the spots will be'c'orrectly positioned to enter the raceway. The plates forming the raceway. are twisted longi tudinally for 180 as shown. from the posi tion. Figs. 5, 6 and 7, next the hopper to their position Fig. 3 which shows the delivery end of the hopper whenthe plate (1 lies uppermost.

The cross-bars D of the agitator are carried at the upper end of a shaft 6 provided at its lower end with a bevel gear e that is engaged and driven by a bevel gear 6 fast on the end of shaft D", the inner end of said shaft being sustained in an auxiliary bearing e secured to or forming part of the underside of the arm I), said cross-bars having auxiliary arms 6 0", e, of" coiled wire, crossing the trough, while the arms c", e are so inclined as to sweep over the beveled or concaved top d of the brid e and up the convexed edge d and being de lected meet any spots improperly placed or clogged in a bunch at the end of the horn, and as the ends of the deflected. arms cross the spot trough they assume their normal-position and kick the bunched spots, scattering the same away from the groove 11"" at the u per end of the bridge, letting the legs of suc 1 spots as ride properly in the trough. enter said groove and the raceway.

The head of the machine has a hole to receivc the shank f of a spot positioning gage which may be adjusted more or less away from the line of the driver and be held in its adjusted position by a set screwf; the head of each spot after the same hasbeen set in stock lying on the stock support may be made to contact with the lower end of the celtioning device as the stock is moved by hand. over the stock plate from left to right, Fig. 3. In practice the top of the stock support is ad- "he nose and the r support, o inn".
